WEll my car used to be fine...and then it wouldnt lock or unlock...and my dad told me that he got it to lock but still wont unlock...any suggestions??? we already sprayed wd 40 like crazy.....thats how he gets it to lock i guess.....

take off the pannel and see, if its not locking one of the plactic guides couldve fallen out and it wont lock so take the panel apart and follow it and see how it works and you should be able to figure it out
